SPECIEFICATION forming part of Letters Patent No. 694,853, dated March 4, 1902.

Application filed November 20, 1894. Serial No 5291356. (No model.)

To @ZZ whom, t may concern: Y

Be it known that I, GEORGE H. Gonsr, a citizen of the United States, and a resident of NenT York, in the county of New York and State of New York, have invented a certain new and useful Cash-Register, of which the following is a specification.

This invention relates to improvements in cash-registers, and has more particular relation to improvements in registers of the checkprinting type.

The invention consists of certain novel constructions, combinations, and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, which form a part of this specification, Figure 1 represents in side elevation the mechanism coinprising my improved cash-register, the printing apparatus being omitted. Eig. 2 is a plan View of the indicator mechanism. Eig. 3 is a plan of the registering or adding mechanism and the actuator mechanism for the indicator and for the type-wheels. Fig. 4 is a vertical section through the register, taken in the plane indicated by the line 4 4 in Eig. 3. Fig. 5 is a front elevation of the cash-register. Fig. G represents the several tapes of the indicator as displayed. Fig. 7 is a side view of the printing mechanism. Figa 8 is an end view thereof. Fig. 9 is a plan view of the printing mechanism in the position shown in Fig. S.

1 represents the case for inclosing the various parts of my cash-register, which case may be of any form and of any material suitable for the purpose.

2 represents the main plate for supporting the registering or adding mechanism and its appurtenances. Said mechanism consists of the actuating-shafts 3 4 5, each of which is provided with a suitable crank at the outside of the case, which terminates in a pointer for following the gradations upon the scales appearing on the front of the case. These shafts are automatically returnable to zero by means of the helical spr-ings 6, attached thereto and to plate 2. Another plate 7 is provided for supporting the inner ends of said actuatingshafts. ,This plate may be supported in any suitable manner, butis shown supported upon plate 2 by intermediate posts.

Upon shaft 3, between plates 2 and 7, is a sleeve bearing the actuating ratchet-wheel S, the adding-cam 9, and the numbered disk 10. Upon shaft 4 is a similar sleeve carrying an actuating ratchet-wheel11,an adding ratchetwheel 12, an adding-cam 13, and a numberdisk 14. Upon shaft 5 is also a sleeve bearing actuating ratchet-wheel 15, an adding ratchet-wheel 16, an adding-cam 17, and a number-disk 18. To the shafts 3, 4, and 5 are rigidly secured the driving-pawl carriers 19. Suitable detents 20, 21, and 22 are provided, respectively, for the actuating ratchetwheel S and the adding ratchet-wheels 12 and 16. These may be mounted in any suitable way; but for the sake of illustration detent 2O is shown in Fig. 3 as mounted upon plate 2, while the other two detents are shown as mounted, respectively, on posts carrying the adding-levers 23 and 24, respectively. The adding-lever is actuated by cam 9 for driving ratchet-wheel12 and is returned by means of any suitable spring-such, for instance, as spring 25. (Shown in Fig. 4.) The addinglever 24 is actuated by cam 13 for driving ratchet-wheel 16 and is returned by a spring 2G. Adding-cam 17 operates upon ratchetlever 27, pivoted to post 2S, which lever operates ratchet-wheel 29, mounted upon a shaft extending from a projection on plate2 to alike projection on plate 7. The ratchet-wheel 2) is connected to the shaft which also carries a nu mber-disk 30. The detent for ratchet-wheel 29 is shown at 3l as mounted upon post 2S.

The indicator mechanism consists of tapes of any suitable material, upon which may be printed the required numbers which shall be displayed 'through suitable apertures in the case. Each tape is wound upon a springdrum at one corner of the case, as shown in Figs. 1 and 2, and has its free end attached to a roller mounted in the opposite corner of said case. The drum 32 carries the tape 33,

bearing numbers O to 9 for representing cents, and drum 34 carries tape 35, also bearing numbers O to 9 for representing dimes, while drum 3G carries tape 37, bearing numbers from l. to 30 for representn IOO , their respective detent-wheels.

ing dollars. f The rollers to which the free ends of said tapes are connected carry upon the lower ends of their shafts sheaves 38, 39, and 40, respectively. Upon these sheaves flexible connections, such as cords or chains 41 42 43, are wound and have4 their free ends connected to pulleys 44, 45, and 46, sleeved or otherwise loosely mounted upon shafts 3, 4,v

'To this bar 55 is connected a spring 57 for holding the detents 54 in 'engagement with This bar 55 also projects through an aperture in the wall of the case, so as to be operative from the outside thereof. By means of the detent-wheels shafts 3, 4, and 5 are retained inthe position to which they are turned until the bar 55 is moved to the right and the detents connected thereto are released from their respective wheels. Then the actuating-shafts are returned to zero by means of the springs 6.

When the actuating-shafts are moved to register a purchase, the arms 48, 49, or 50 engage pins 47, and pulleys 44, 45, or v46 are rocated with said shafts. This winds the ilexible connections 41, 42, or 43 upon their respective pulleys, thereby rotating the rollers to which sheaves 38,39,or 40 are connected and while winding the tapes thereupon cause venience of illustration assuspended from -plate 2.

rllhese brakes are held upon the pulleys under tension of suitable sprin`gs,as indicated at 61. To release the brakes, I'provide a bar, as `62, mounted in' suitable guides upon plate and provided with pins 63 for engagement with the rear sides of the levers 59. Upon-this bar`62 are mounted detents 64, with which engage, respectively, the arms 48, 49, and 50. From this constructionit will bel seen that when any one of the arms is moved in the initial movement of the register the bar 62 willbe moved, and allthe brakes will be released from their respective pulleys,

allowing the latter to be-actuated by theunwinding'of the cords 41, 42, or 43 under the influence of the springs upon the roller-or` rollers carrying the tape or tapes displayed.v It will be observed from the above that after one of the pulleys hasbeen set that it is held in position by both its respective brake and Vits pawl 54. A subsequent operation of one mount upon plate 60 an arm 65, which shall engage a projection upon said bar and also carry a spring-hammer 66 for striking the gong 67, also mounted vupon said plate 60. Said ham mer in its normal position rests, as shown in Fig. l, upon the stud for mounting the gong and is thrown againstthe gong byv movement of the bar 62 to the right. This movement of the bar causes its projection to pass under the lower end of the arm 65, so that the spring-hammer 66 willfall backagain upon the mounting-stud of the gong. UNow when the bar 62. moves to the left again the spring-hammer will give to allow the projection of said bar to force the arm 'upward and pass under the sameto its'original position. I also propose to operate a drawer-locking device by the movement of thebar 62. Said locking device consists of .a rock-shaft 68, mounted in suitable bearings at the front and rear Walls of the case and provided with a locking-arm 69, which engages the inner side of the rear wall of the money-drawer when in place. Upon the rock-shaft 68 is also mounted an upwardly-projecting arm 70, which is held by a spring 7l in engagement with a pin 72, carried by bar 62. As bar 62 is moved to the right it forces arm 70 over and raises locking-arm 69 free from the money-drawer. the locking-arm 69 is also returned to its normal position. Then as the money-drawer is returned to place its rear side 4engages with the inclined forward projection of. arm

69 and raises it up in the act of kpassing by it,y

the spring 71- returning it to place again and locking the drawer.

Any suitable springs .may be used for forcing the money-drawer out as the locking-arm is raised; but for the sake of illustration I have shown'them as plate-springs 7.3.'

The mechanism asthus far described may be used for various purposes' where itis not necessary-or desirable to issue checksvforthe amounts of purchase; but forsuchv use as makes it necessaryto issue checks Ifprovide a printing mechanism which may be operated in connection therewith l and may be readily attached or detached from theregistering and indicating mechanism. .Such printing mechanism consists of the usual typewheels, as indicated at 74, 75, and 76in Figs. 7,8, and 9. .'Wheel 74 is mounted upon a shaft 77, supported in suitable bearings.

mounted upon a bar 78, attached to plate 7. Wheel 75 is mounted upon a hollow shaft 7 9,A

lOO

Upon the :return of bar 62 IIO sleeved upon shaft 77 and journaled in bearings rising from said bar 78, and wheel 76 is mounted upon a hollow shaft S0, sleeved upon said shaft 79 and mounted in a bearing also connected to said bar 78. Said sleeve-80 may also have a bearingin the wall of the printing-case 81, which is shown as screwed to the side of the register-case. Said shafts carry upon their inner ends bevel-gear, as shown, which mesh with corresponding bevel-gear mounted upon the actuating-shafts 3, 4, and 5, respectively, so that the type-wheels shall move in unison with the respective actuatingshafts of the register.

The printing mechanism cooperating with the type-Wheels, as stated, is mounted in a casing 81 and consists of a platen 82, pivoted at one end upon a shaft extending from one wall to the other of the printing-case and resting at its free end upon a stop S3, similarly located. A shaft 84 extends through the printing-case and is provided on the outside with a crank 35, and to this shaft is secured a cam 36 for forcing the platen against the type.

The type may be inked in any suitable manner; but for the sake of illustration I have shown it as inked by means of a type-ribbon 87, carried by rollers 83, which are mounted in bearings upon a plate-spring 89, secured to a projection upon the wall of the case. This plate-spring carries in suitable bearings feeding-wheels 90, mounted at either side of the type-wheels. For cooperation with these feeding-wheels cams, as 91, are mounted upon the shaft Set.

The paper may be mounted in a roll 92 in any suitable position upon the case of the register and may, if desired, be included within the printing-case, as indicated in dotted lines in Fig. 7. The paper passes over the platen between it and the ribbon, as indicated at 93, and when printed issues through a slot 94 in the side of the printing-case.

The operation of the printer is as follows: The type-wheel having been set bythe operation of the register, crank 35 is turned in the direction of the arrow in Fig. 7, causing cam 86 to force the platen upward, carrying the paper and ribbon against the type. Then as the crank is continued in its rotation said cam recedes from the platen, and as it recedes cams 91 catch the edges of the paper lbetween them and the feeding-rollers 90 and feed the paper forward the required distance, the operating-surface, consisting of the cams 91, being properly proportioned to feed only so much paper as is necessary. The paper may he perforated upon the roll, so that the checks may be easily torn therefrom, or it may be imperforate and the checks may be torn olf against the edge of the slot 94.

For the operation of the releasing mechanism for the actuating-shafts of the register I mount a cam, as 95, upon the shaft 84, whose iiange 9G shall be formed as shown in Figs. 8 and 9 and shall extend over a portion of the diameter of said cam. This iange will engage in a slot 97 on the projecting end of bar 55, so as to draw said bar outwardly and release the detents 54 from their wheels just as the printing of the check has been accomplished and while the feeding of the paper is taking place, thus allowing the actuatingshafts of the register to return to Zero simultaneously and be in position for the next registering operation.

1n case the register is used without the printing mechanism a knob, as 9S, (shown in dotted lines in'Fig. 1,) may be connected to said bar 55 for releasing the actuating mechanism of the register.

The numbered disks 10, 14, 18, and 30 may display their figures through suitable apertures in the plate 7, as indicated at 99 and 100.

Each adding-cam 9, 13, and 17 is'divided into three lobes, each lobe representing ten digits, and the ratchet-wheels 8, 11, 12, 15, and 16 bear eachl thirty teeth vto correspond with the adding-cams. From this it will be seen that in ringing up a purchase of nine cents it is only necessary to rotate the shaft 3 through one-third of a circle,while in ringing up ninety cents it is only necessary to rotate the shaft a through one-third of a circle; but in ringing up any number of dollars from one to thirty shaft 5 may be turned through the required arc.

The adding mechanism is the same as in many other registers. The maximum amount allotted to one actuating-shaft causes a movement of one tooth upon the adding-ratchet of the next shaft, and so on to shaft 5, where the maximum amountallotted tosaid shaft being turned in will actuate the adding ratchetwheel 29 through three teeth. 1 have shown the adding ratchet-wheel 29 as carrying fifty teeth and adapted to register ten dollars for each tooth, so that the register as represented is capable of registering five hundred dollars plus the sums indicated by the number-disks 10, 14, and 18.

The indicator is constructed to represent purchases from one cent to thirty dollars.

The operation of the device, in brief, is as follows: Supposing a purchase of one dollar and twenty-five cents to have been made, the shaft 3 is rotated until its crank points to number 577 on the scale 101 and the shaft et is rotated until its crank points to 20 on the scale 102 and shaft 5 is rotated until its crank points'to 1 on scale 103. This will cause tape 33 to unwind and display the figure 5 at the opening 10st and tape 35 to unwind and display the iigure 2 at opening105 and tape 37 to unwind and display figure 1 at opening 106. Crank S5 of the printing mechanism is then rotated, the check printed, and as the check is about to issue bar `55 is operated by cam 95, which allows the actuating-shafts 3, 4, and 5 to return their cranks to zero, which in returning operate the register, the indicator still remaining as set and exhibiting 1 at the dollars-opening and 25 at the cents- IIO openings. At the'hinitiabmovement of any one ofijthe shafts 3, 4, or 5 in ringingup a` subsequent 'purchase bar 62 will be moved to from their respective pulleys, which pulleys ,being free to rotate will allow the springs on the drums 32, 34, and 36 to wind up their respective tapes, returning the indicator' to zero. The subsequent purchase will then appear as previously described. s l

In constructing this machine many changes in the proportions and arrangement of the various parts may be resorted to without de parting from my invention, the gist of which resides in the progressively-moving indicator returnable to zero at the initial movement of each act of registration and in providing for the simultaneous and automatic return of the actuating mechanism of the register, and in the operation in connection with the indicator of a printing device and in so constructing and connecting these principal features that a perfectly-operating cash-register may be produced which shall be capable of registering and indicating any number of cents, and at the same time shall be simple in construction and easy of operation. The printing mechanism is so designed that it may be readily detached and the indicator and register used without it. tached to the outside of the case; but obviously it might be located within it.

The machine as illustrated is designed for placing upon a back counter and to be operated from the front. By obvious changes, however, it may be made operablefrom the rear side and have upon its face simply the indicator-openings.
